Patented Nov. 14, 1939 REFRIGERATOR WINDOW Paul H. Brinkoeter, San Antonio, Tex., assignor to Ed. Friedrich Inc., San Antonio, Tex., a corporation of Texas Application January 9, 1939, Serial No. 250,049

1 Claim. (01. Bil-56.5)

My invention relates to refrigerators and more particularly to the multi-pane windows used in the'front of the case, although the invention is 15 adjacent compressible faces of the panel spacers.

Other objects will in part be obvious and in part be pointed out hereinafter.

To the attainment of the aforesaid objects and ends the invention still further resides in the 20 novel details of construction, combination and arrangement of parts, all of which will be first fully described in the following detailed description, and then be particularly pointed out in the appended claim, reference being had to the ac- 25 companying drawing, in which:

Fig. 1 is a front elevation of the window.

Fig. 2 is a rear elevation of the same.

Fig. 3 is an enlarged detail cross section on the line 3-3 of Fig. 1.

3@ Fig. 4 is an enlarged detail front elevation of one corner of the window before placing the outer or finish strip in position and before the wax is poured.

Fig. 5 is a detail perspective view of one end 35 of one of the spacer bars or strips, a part being shown in section.

In the drawing inwhich like numbers of reference indicate like parts in all figures, I is the main frame on one side of which is permanently m secured an abutment frame composed of a bottom bar 2, and side and top bars 20 secured permanently together at the corners, thus leaving an open channel 3 in the frame into which the glass panels H5 and spacing strips 6 are set.

45 The abutment frame 2, 20, is chamfercd as at are'also grooved at 8 thus forming a T-shaped head I which is embraced by a rubber cover I2 having parallel sides against which the glass panels [6 lie while the shoulders 9 in part lap the edges of the panels (see Fig. 3). Those faces '5 of the stripslB and of the cover l2 which contact the glass are preferably grooved longitudinally as at l3 to act as vacuum cups and to this end the rubber of the exposed faces of the covers which extend from panel to panel are 10 continued over the ends of the spacing strips l6 as at H and are tacked or otherwise held to the endsof the strip as at l5, thus closing the ends of the grooves 13.

Screws [0 secure the respective strips Hi to one another and to the abutment frame 2, 20.

Fnish strips l'l, chamfered to receive rubber strips l8 and in part to lap the edges of the panels l6 close the channel 3 at its outer end and are secured by screws similarly to the strips 6.

The strips 6 between two panels do not fit the channel 3 tightly but may be kept spaced therefrom by the use of suitable shims II at intervals (see Figs. 3 and 4) and the adjacent strips 6 are spaced slightly apart by othershims II, nor are the shoulders 5 and 9 intended to contactv the edges of the glass panels but on the contrary are spaced slightly therefrom.

After the parts are assembled the spaces between the strips 6 and I1 and between the strips and frame I, 2, 20, are filled by pouring melted wax into the same to fill the said spaces and hermetically seal the same.

On the front of the case the finish strip ll along the bottom flight is covered, preferably, by a suitable metal'or porcelain shield 23, secured by screws 24, to give a finished appearance and the space between the shield 23 and the adjacent glass panel [6 is filled with wax 19 whereby the shield 23 will also serve as a water shed. 40

A somewhat similar shield 2| is secured at 22 to the rear of the-case and sealed with wax l9 and serves as a water shed to deflect downwardly and inwardly any condensed moisture which may form and rundown on the exposed face of the innermost glass panel 16.

In assembling, the frame is laid down on its inner face (right hand side Fig. 3). The rubber strips or gaskets l8 are placed in the chamfer 4 and a panel l6 laid in place thereon. {Next a set of spacer strips 6 are placed in position, (using shims ll if desired) and screwed tight to the abutment frame. This expresses air from the grooves l3 which may then act as suction-cups; the next panel [6 is then put in place and the next set of strips 6 secured by screws I 0 to the preceeding set and so on until the entire assembly has been perfected.

Melted wax is then poured into the spaces between finish strip and frame and runs into all joints or crevices and fills the same. The wax on congealing thus efiects a hermetic seal which together with the rubber l8--|2 prevents the air fromleaving the spaces between the panels and the outside air from entering the same (breathing).

The air between the panels It; thus in truth becomes dead air and acts as a thermal insulator to prevent condensation and fogging of the glass.

It will be seen also that the covers I! extend down over the parallel sides of the head I and give a large area of contact with the glass panel.

From the foregoing description taken in connection with the accompanying drawing it is thought the construction and advantages of the invention will be clear to those skilled in the art.

What I claim is:

A multi-paned window of the character described including a main frame the inner perimeter of which has a channel open at one side; a plurality of glass panels for'said frame arranged with their marginal edges extending into said channel; spacing strips intermediate of the glass panels and extending into said channel beyond the edges of said panels; rubber covers over the side faces of said strips opposing the glass panels and the faces extending from panel to panel, the sides of said covers against which the panels lie being formed with grooves; and means securing successive sets of strips to adjacent sets to clamp the panels between the same; said frame including an abutment frame; sealing means between said abutment frame and the panel adjacent thereto; and a set of finish strips, and sealing means between the finish strips and the adjacent glass panel, said covers of the spacing strips extending over the ends of the strips and closing the ends of said grooves.
